Re: Ultramatic - stuck in park

Definitely a good trick to remember but if you still have the auto park relay, just in case there is a problem with the auto park function and relay is not energizing when key is turned on, to prevent an issue I would disconnect the green wire off the end terminal of the relay before doing this step. If the auto park circuit is trying to keep it in park and you manually force it to try and go the other direction there will be a conflict. Best case motor will buzz or vibrate before breaker can open, worst case damage could happen.

Once you do this procedure and if actuator starts moving properly it might be a good idea to follow the procedure in the Twin Ultramatic supplement section of the manual to check or adjust the actuator anti hunt screw.
